A question of world health (3)
I believe the answer is:
who
This might be a double definition.
'a question' is the first definition.
(who is a question word)
'world health' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'of' is the link.
Can you help me to learn more?
(Other definitions for who that I've seen before include "Alien doctor" , "The - - , rock legends" , "international medical group" , "UN health agency" , "Which person?" .)
